The declining population of bees in this city in Holland is a real issue. What do you think of this solution to attract more honey bees and bumblebees?

According to Lonely Planet, 316 bus stops have been transformed into 'bee stops' in the city of Utrecht, the country's fourth-largest city in Holland. Each roof is filled with wildflowers and sedum plants.

"Bee stops are tended to by workers who drive around the city in electric vehicles. But the scheme requires little maintenance because the roofs are mainly composed of sedum plants, which are a favorite among pollinators and require very little water to survive. To improve facilities for human visitors, the bus stops have also been fitted with energy-efficient LED lights and bamboo benches."

In addition to the city's solution, residents can also apply for funding to transform their own roofs into bee sanctuaries. How cool is this? All cities should encourage their residents to plant bee-friendly flowers.
